You can put both the Tufo and Vittoria in a tire before you ride, but some people note that the tire is much less supple after the sealant is in. Plus, don't use your CO2 cartridges to inflate the tire with the sealant in it. The CO2 blast makes the sealant very hard and the tire will feel like a brick.

So when I wil be using a tube on training I can't use a CO2 cartridge? And how long can you leave the sealant in the tube and how long does it keep working?

I have already used a CO2 cartridge after a pit stop injection.

But in this case, you have to wait a little bit after the pit stop injection because if you immediatly inflate with a CO2 cartridge, the pressure is too high and the sealant of the pit stop is push away from the hole.

I’ve found the Tufo stuff to be OK, but not great. It works, but won’t hold anything above about 85-90 PSI without squirting. It’s enough to get you home, but not spectacular. It’s fine for races (flat means you’re done) or training (you’ve got time), but not the solution I want for running tubs at the Marmotte or something like that, where I don’t want to stop to put on a new tub and certainly don’t want to descend on under-inflated wheels.

I’m interested in the Pitstop option for two reasons: I’m told it can hold higher pressures, and I’m not stuck on Tufos. Can anyone confirm the former?

Both are latex and can be used in anything that latex will repair. I like the pitstop as it will also air up your tire. I got a leaky grifo cross tire and did the pitstop and the tire holds air like new. The pitstop could also be multiple use. I filxed the leak with half the can and used the other other half in another tire just for testing purposes.

I've used both the Tufo and Vitoria product. I find the Vitoria works better than the Tufo, but Stan's - found at www.notubes.com - works far better than both of them. I've got a gash is in a Tufo Flexus cross tire that was nearly 4 mm long and it sealed it. I've sealed a couple of road tubulars with it that the Vitoria product wouldn't work on. The advantage to the Vitoria product is that it's presurized and will both inflate and seal which is crucial on the road. For punctures that the Vitoria can't handle give the Stan's a try before discarding the tire. Sometimes, you have to inflate the tire a few times and it may take overnight, but I find it works on more substantial punctures.
